They do reconnect when I click them in an explorer, but I have timed backup scripts (Windows .cmd files) running which wake the computer and need to access one of those drives and which fail at file access.

I was hoping for a way where it wasn't necessary for the script to know the location of the mapped drive (i.e. to be able to just move \\server\share somewhere else in the future without having to update the scripts). something like "net reopen x:" (I'm just making this up) or a clever trick to that end.
